Question

What three types of Ortho K lenses use software-based fitting?

b) Corneal reshaping lenses, hybrid lenses, and alignment lenses

c) Reverse geometry lenses, myopia control lenses, and orthokeratology lenses

d) Overnight lenses, daytime lenses, and extended wear lenses

Answer 1

It's important to note that various vision problems like myopia and hyperopia can be corrected with appropriate lenses or surgical interventions such as LASIK, which reshapes the cornea.

Step-by-step explanation:

The three types of Ortho K lenses that use software-based fitting are:

• Paragon CRT
• Euclid Emerald
• Bausch & Lomb Vision Shaping Treatment

Myopia (nearsightedness) and hyperopia (farsightedness) are common vision problems that can be corrected with lenses that help focus light on the retina. For myopia, a concave lens is used to spread out the light rays, improving focus. In contrast, hyperopia is corrected with a convex lens, which converges the light rays for better focus.

Laser vision correction, including procedures such as LASIK, has become a popular method to correct these vision problems surgically. This process involves using high-intensity electromagnetic radiation to ablate and reshape the cornea, thus altering its power to correct vision.
